An important factor in choosing a car - the volume of the engine

Every year the number of cars on our roadsinexorably growing. And this is not surprising. Automobile transport is the most practical and comfortable, if you do not take into account traffic jams. Someone is changing cars like gloves. For such people uninteresting characteristics. Give them prestige and glamor. And there are ordinary hard workers who are hoarding on the car for several years. Such people simply have to understand the "stuffing" of the vehicle.

What car without the "engine"? It is the engine that is the heart of any four-wheeled vehicle. The unit is characterized by its power. So, the volume of the engine is a set of volumes of all cylinders. Before buying a car you need to clearly understand which engine will be under the hood. Depending on the fuel used, the engines are divided into gasoline, diesel and hybrid.

In our country motorists prefer the firsta type. Now the petrol engines come with an injector and fuel injection distribution system. Carburetor copies are a thing of the past. Fans of SUVs prefer diesel engines. These units produce a higher torque, resulting in a significant increase in power. Cars with diesel "engines" in our country are unpopular. There is a reason to take the "engine" on diesel, if you overcome 50 or even more than thousands of kilometers.

With respect to hybrid plants,power supply are different. Basically, this engine works on solar energy, electricity and hydrogen. Of course, the volume of the engine is so small. However, the cost of fuel will not be. It will be necessary to fork out for the installation, which will process energy. Unfortunately, in Russia such cars are rarely found on the roads. It's all about the high cost and the problems that arise during the repair. There are no specialized technical service stations in the country.

In order to understand what the volume isengine, you need to explain in simple terms the principle of operation. There is a combustion chamber. In this space, a fuel mixture and air are placed. One of the walls of the chamber is the piston. He's mobile. With the spark plug, the fuel ignites. The energy that was generated as a result of the explosion drives the piston. The latter forces the crankshaft to move. As a result, the car picks up speed. Of course, this explanation, let's say, "on the fingers." But this is enough to understand that the volume of the engine, in fact, is the volume of the combustion chamber.

That's not all. You should know what is the working volume of the engine. This is the sum of the working volumes of all cylinders of the piston engine of internal combustion. The number of cubic centimeters determines the capacity of the unit. Of course, the engine displacement is an important criterion that determines the power characteristics. Proceeding from this, cars are divided into minicars (up to 1.1 liters), subcompact (1.3-1.7), medium-sized (1.8-3.5) and large-scale (over 3.5 liters). This distribution - a conditional, it applies to gasoline "engines". With diesel engines, the picture is slightly different.

At the moment, the idea is quickly moving forward,based on the variable engine displacement volume by means of an electronic system that can shut off a pair of cylinders at low loads to save fuel. A small part of American SUVs is equipped with such a system. This saved 20% of fuel. There are developments to change the working stroke of the piston mechanically. However, this innovation did not reach beyond the experiment. We must state the fact that progress does not stand still, and soon scientists will please us with their useful inventions in the field of engineering. However, engine capacity will be a significant indicator of capacity at any stage of development.
